Esophageal Granular Cell (Abrikossow) Tumor: Macroscopic Appearance and Endoscopic Management (Video)

Abstract

Granular cell tumors are rare but benign submucosal tumors of the esophagus. Usually tumors are rather small and do not cause symptoms. We demonstrate a case with typical macroscopic appearance at endoscopy and endosonography. Important differential diagnoses are leiomyoma, and gastrointestinal stroma tumors. Although the patient had no symptoms, he insisted on a complete removal of this tumor. After careful inspection of the submucosal tumor with high-definition white light endoscopy and endosonography we performed endoscopic resection. No post-procedural complications were observed.
